Question

The cost of 15 identical article is ₹ 1050, how many articles can be bought for ₹ 5250

• A. 45
• B. 75
• C. 45
• D. 85

Answer 1

The correct option is B

75

More the items , more the cost.

Hence it is a case of direct variation.

Let the number of items that can be bought for ₹ 5250 be $x$.

Then,

Hence $\frac{15}{x}$ = $\frac{1050}{5250}$

$15\times 5250$ = $x\times 1050$

$⟹$$x=\frac{15\times 5250}{1050}$

$⟹x=75$

$\therefore$ 75 articles can be bought for ₹ 5250.
